Hello friends.
Here are some pictures of our progress to date. We are beginners and did the best we could with the information available given the time limits imposed by cold weather in January on the East coast.
The oven dimensions are 40 length by 30 width inside and there are 60 inches from the back of the oven to the ash drop.
We built a steel reinforced concrete block wall on each side of the barrel walls to address the arch expansion problem. There is 3 inch cal-sil board between the oven and the blocks, plus a layer of blanket as in WJW's design.
Between the back of the oven and the block walls are 3 layers of blanket, and the back block wall is tied in the the side walls.
We built a partial heat stop between the top arch of the oven and the chimney with bricks we made of cal-sil board.
I could use suggestions for insulating the front of the barrel- I was planning to layer on more blanket.
The vermiculite/perlite mixture goes over lath, as I understand it, as chicken wire rusts, correct?
I have thermocouple wire that I wanted to embed in the hearth, but one thing led to another and it didn't get done. Could I drill a hole under the hearth with a long drill bit, and perhaps embed another under the blanket at the top? That way I would have some way to measure heat saturation.
It seems I will need longer tools that those that are readily available. Any suggestions for addressing that problem?
Thanks so much for all your expert help.
